Crossovers are electronic circuits or components that divide the audio signal into different frequency bands and route them to the appropriate drivers (e.g., tweeters, mid-range, woofers) within a loudspeaker system. They ensure that each driver receives only the frequencies it is designed to handle, preventing distortion, phase issues, and damage to the drivers. Well-designed crossovers contribute to seamless integration between drivers, smooth frequency response, and accurate sound reproduction across the entire audible spectrum.
